Rock 4 SE wrong Hdmi Resolution when TV is started later

Hello,

I have a Rock 4 SE runnning librelec 10.0.2 and still have a problem with Hdmi and the resolution.

When the TV is on, and the rock starts, the resolution (HD) is set correctly, but when the Rock 4 is recording and I turn on the TV later, a smaller resolution is set. The recording file has the correct resolution accept the gui-resolution is wrong

The Rock can not read the correct values from the TV off. Does it needs an edid or something like that?

How can I fix this ?

I hope someone can help me
